Answer:
Is this a general equation?
76/9 = 8.444444444444 > 8.0 or 8.45
Answer: there is almost no relationship between x and y.
Explanation:
The coefficient r tells how well the data fix into the model chosen.
A value r = 1 indicates a perfect positive linear relation.
A value r = - 1 indicates a perfect negative linear relation.
Intermediates values may be interpreted more or less in this way:
1) 0.7 < |r| < 0.7 => strong relation between the variables
2) |r| ≈ 0.5 moderate relation between the variables
3) |r| ≈ 0.3 poor relation between the variables
4) |r| ≈ 0 non-relation between the variables.
The answer would be 25...
Think about it, switch 25 with z
Answer 25 - 3 = 22
Correct
